Although a domestic trial in Japan revealed that Absorb bioresorbable vascular scaffold (BVS) has no inferiority to everolimus-eluting stent (EES) cohort in the primary endpoint of the target lesion failure at 12 months, the scaffold/stent thrombosis (ST) rates with the BVS at 24 months were higher than those with the EES (Absorb BVS 3.1% vs. EES 1.5%), the ST rate of 3.1% with Absorb BVS is not an acceptable level in Japan. A cause-of-ST analysis revealed that cases in which diagnostic imaging and ensuing post-dilatation had been performed appropriately had lower ST rates than those without such management (within 1 year: 1.37% vs. 7.69%, from 1 to 2 years: 0.00% vs. 8.33%). ⋯ Regulatory approval was given conditionally to initiate rigorous post-marketing data collection in order to ensure the proper use of this device in limited facilities. The One-year Use-Result Survey in Japan for the Absorb BVS revealed no instances of ST. This approach to reducing the premarket regulatory burden of clinical trials and enhancing the post-marketing commitments of medical device regulation is useful for expediting patient access to innovative medical devices.

A 72-year-old man with intractable left shoulder pain due to bone metastasis from cholangiocellular carcinoma was admitted to our hospital. Computed tomography showed an osteoblastic metastatic lesion of the left scapula. ⋯ After the intervention, the shoulder pain was alleviated without any procedure-related complications, leading to a reduction in the opioid dose. This case suggests the efficacy of transcatheter arterial embolization using microspheres for palliating pain from bone metastasis.

We herein describe an 82-year-old patient who presented with proteinuria and systemic edema. He was diagnosed with minimal change disease (MCD) and was found to have stage III pancreatic cancer. ⋯ After two months of chemotherapy, computed tomography indicated a partial response to the therapy. MCD can occur as paraneoplastic syndrome in patients with malignant disease, and chemotherapy can be effective for MCD associated with paraneoplastic syndrome.

A 65-year-old man diagnosed with locally advanced pancreatic cancer underwent distal pancreatectomy and combined portal vein resection. One month after surgery, contrast-enhanced magnetic resonance imaging revealed multiple liver metastases. ⋯ As a result, we administered hepatic arterial infusion chemotherapy comprising gemcitabine plus 5-fluorouracil because the residual tumor was limited to liver metastases. The progression-free survival period was 7 months, and no drug-related adverse effects were noted during the treatment.

A 53-year-old woman was admitted to another hospital because of a 2-month history of repeated chest pain and breathlessness. Laboratory examinations demonstrated the presence of hypereosinophilia (absolute count of 6,500/μL). An endomyocardial biopsy confirmed eosinophilic infiltration with myocardial destruction. ⋯ Based on the multimodal imaging and histopathological findings, the final diagnosis of "Löffler pancarditis" was made. After the introduction of steroid therapy, the left ventricular contractile function significantly recovered. Furthermore, the late gadolinium enhancement of the visceral pericardium had attenuated.
